Sapienza and Wheeler (2006) discussed the potential functional outcomes of expiratory muscle strength training and the framework of neuroplasticity as it relates to strength training programs. The authors reported that expiratory forces generated with more efficiency may increase expiratory driving pressure, which may produce improve cough flow, sound quality and durations, and overall speech naturalness. This explanation may indicate potential benefits of EMST for individuals with voice disorders and provides a rationale for future research with this population. The authors also reported that strength training can improve motor performance through neuroplasticity if the stimulus has an intensity (load and duration) to cause a change in muscle
